Product Overview
A flat natural rubber washer provides a custom rubber layer around a central opening. The inner diameter, outer diameter, and thickness should correspond to the mating components and available space. Its flat section needs support across the intended contact area as the fastening stack closes.
Check the clearance around the fastener or shaft and the width of the receiving face. A washer that extends over an unsupported opening can deform differently from one seated fully on a flat surface. The selected natural rubber compound also needs to suit the medium, temperature, and cleaning conditions at that location.
Install the washer cleanly without folding or stretching it to fit. Keep it centered during tightening and avoid using excess force to compensate for an unsuitable thickness. If the part serves a sealing role, evaluate the complete joint under its intended operating conditions. During maintenance, inspect the washer and mating faces for damage, and replace it with the correct profile so the original spacing and contact arrangement are maintained.
- Material options
- Natural rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. A washer that extends over an unsupported opening can deform differently from one seated fully on a flat surface.
- Custom dimensions
- The inner diameter, outer diameter, and thickness should correspond to the mating components and available space.
- Fit & assembly
- Check the clearance around the fastener or shaft and the width of the receiving face.
- Use & inspection
- During maintenance, inspect the washer and mating faces for damage, and replace it with the correct profile so the original spacing and contact arrangement are maintained.

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
